Hey, can some1 please I'd these funny furry cotton wool looking growths in mu sump and overflow area, one side is attached to the surface, looks like some kinda nest thingy but growin all over diferent sizes......

@viper357 ... Hey thanks dude, checked it out , correct u are!... So its scypha,,,,, good or bad, internet give diferent opinions, wat causes it? Should I get rid of it? Is having scypha indirectly alertin me of somethin I should check for?....any1 with scypha experience?

I sometimes have loads of these, they seem to come and go, not sure why, but they are harmless filter feeders and eat small particulate matter that floats around in your water, I'm guessing they would do well in well fed productive tanks as there will be more in the water column for them to feed on. But all in all one of the good guys to have, harmless.
